A nurse is caring for a client who has liver cirrhosis with ascites, bleeding esophageal varices, and portal hypertension. The nurse recognizes which of the following laboratory findings as indicating the client's gastrointestinal (GI) tract is digesting and absorbing blood?
Decreased bilirubin
Decreased chloride
Elevated blood urea nitrogen (BUN)
Elevated HbA1c
The Correct Answer is C
Rationale:
A. Decreased bilirubin is unrelated to digestion of blood in the GI tract.
B. Chloride levels do not indicate blood digestion.
C. When a client with esophageal varices bleeds into the GI tract, the digestion and absorption of blood proteins lead to increased nitrogen load, reflected as elevated BUN.
D. HbA1c reflects long-term blood glucose control, not acute digestion of blood.

Correct Answer is C
Explanation
Rationale:
A. An obstruction of the common bile duct causes dark amber or tea-colored urine due to increased bilirubin excretion.
B. The gallbladder and common bile duct are located in the right upper quadrant, so pain is typically felt there.
C. Obstruction of the common bile duct prevents bile from reaching the intestines, impairing fat digestion and absorption, leading to steatorrhea (fatty, foul-smelling stools).
D. Ecchymosis is not a typical sign of common bile duct obstruction. It may indicate coagulation disorders, but it is unrelated to chronic cholecystitis.
